* European shares down 1 percent
* Yen gains, dollar generally weaker

LONDON, Feb 11 (Reuters) - Investors voted with their feet against the newest U.S. bank bailout plan on Wednesday, knocking stocks lower, widening credit spreads and boosting safer-haven currencies.
There was general concern that the $2 trillion plan, unveiled by U.S. Treasury Secretary Timothy Geithner on Tuesday, was not sufficiently clear about how it would cement the security of the shaken U.S. financial system.
"They've given it a fancy name (but) there's a huge amount of uncertainty," Peter Dixon, an economist at Commerzbank in London, said of the U.S. plan.
The U.S. Senate also voted to pass an $838 billion economic rescue plan on Tuesday, but investor reaction clearly showed greater concern about financial security.
World stocks as measured by MSCI <.MIWD00000PUS> fell 0.6 percent after losing 3 percent on Tuesday. Emerging market shares <.MSCIEF> were down 1.5 percent.
U.S. stock futures were flat to weaker <SPc1> a day after Wall street fell sharply following Geithner's unveiling of the plan.
In Europe the FTSEurofirst 300 <
> was down 1 percent [ ]. Japan's market was closed for a holiday.Disappointment over the bank plan could also be seen on credit markets, where spreads widened, indicating subdued risk appetite.
Spreads on Merrill Lynch's 6.875 percent notes due in 2018, for example, widened to 500 basis points over Treasuries on Tuesday, out from 474 basis points before the plan was unveiled, according to MarketAxess.
The mood carried over into Europe and Asia credit markets on Wednesday.
"It is quite clear from Geithner's words that a lot of work remains to be done before the plan is fully operational," Calyon credit strategists in Asia commented in a note to investors.
"In addition, Geithner insisted once again on the fact there is no easy way (out) from this banking crisis."
CAUTION
The yen gained, as it has recently when investors become cautious.
The dollar fell 0.5 percent to 90.04 yen <JPY=>, having shed 1.3 percent on Tuesday. The dollar also fell against the euro <EUR=>, with the single European currency gaining 0.3 percent to $1.2966.
Euro zone government bond futures jumped 86 ticks as investors moved to relative safety.
The interest rate-sensitive two-year Schatz yield <EU2YT=RR> was down 6 basis points at 1.406 percent. The 10-year Bund yield <EU10YT=RR> was down 8 basis points at 3.264 percent.
